Automatic Centre Punch

grabcad

A remodeling - as accurately as possible - of a centre punch with a compression spring loaded automatic function.A tool with a simple, interesting and effective mechanism.Notes:All threads are modeled with theoretical values of M10,5 and a pitch of 1 mm.Any clearance between bolt and nut is non-existent.The neutral lenght of the compression springs are:38 mm for the action spring21 mm for the conical wounded springTry to understand why this center punch can works properly.I hope, that my model can show the function in a way without an animation.If anybody is able to animate my model in a self-explanatory way, please try it out. I'm not able to do such a complex animation by myself.A lot of thanks thanks would be sure.The model is available in following data formats:STEP-file (.stp) of the complete assembly and all native files (.prt) and (.asm),together in a (.zip)-folder, for users of »PTC Creo Parametric 2.0«
